PERRY BARTLETT, OF SPOKANE, \VASHINGTON.

AXLE LUBWCATOR.

SPECIJEIUATIlIOJiI forming part of Letters Patent No. 668,081, dated. February 12, 1901.

Application filed April 19, 1900- Serial No. 13,556. No model.)

to oil 7/71/0727, it til/my con/corn:

Be it known that l, PERRY BARTLETT, a citizen of the United rltates, residing at Spokane, in the county of Spokane and State of VVashiugton, have invented new and useful Improvements in Axle-Lubricators, of which the following is a specification.

My invention relates to improvements in aXle-lubricators; and it consists in a certain novel construction the utilityaud advantages of which will be fully understood from the following description and claims when taken in coniunction with the annexed drawings, in which- Figure 1 is a view, partly in elevation and partly in section, illustrating a wagon-axle equipped with my improvements. Fig. 2 is a top plan view of the same.

deferring by letter to the said drawings, A is a wagon-axle provided with suitable spindles a, and l3 ii are the reservoirs or lubricant-receptacles of my improvements, which are preferably provided with apertured ears I) and connected to the rear side of the axle by screws 0, passed through said ears, as shown. The said reservoirs or lubricant-receptacles are designed to be filled in any preferred manner with axle-grease or other suitable lubricant and are connected at their outer ends to tubes O, which lead to and through the spindles a to a point at the upper side and about midway the length thereof, as shown.

D D" are followers which are arranged and adapted to be moved in the reservoirs or receptacles B and have for their purpose to expel the grease or other lubricant from the said reservoirs and force the same through the tubes C to the axle'spindles as it is needed thereon. The said followers D D have stems d d, respectively, which extend through the inn er heads of the reservoirs and are threaded, as shown-that is to say, the stem (Z of follower D is provided with left'hand threads 6, while the stem (1 of follower D is provided with right-hand threads. The follower-stems extend through suitable guides g on axle A and are connected after the manner shown by a turnbuckle E, which is provided at one endwith right-hand threads and at its opposite end with left-hand threads. When this turnbuckle is turned in one direction, it is obvious that the followers D D will be moved inwardly or toward each other, while when it is turned in the opposite direction the followers will be moved outwardly.

In practice the receptacles or reservoirs B are charged with axle-grease or other lubricant while the followers D D are at or adjacent to the inner heads of the receptacles, and then as lubricant is needed on the axle-spindles the turnbuckle E is turned to move the followers outwardly or in the direction indicated by arrows in Fig. 1. When the followers are thus moved outwardly, the grease or lubricant is forced through the tubes 0 to the axle-spindles and is spread over the same by the rotation of the wheels (not shown) thereon.

It will be readily appreciated from the foregoing that the receptacles B are adapted to hold a large quantity of axle-grease or other lubricant without liability of dust, grit, or other foreign su bstauce being com mingled therewith and that a greater or less amount of the lubricant may be forced to the axlespindles as the conditions require.

It will also be observed that my improvements are simple and inexpensive in construction, are susceptible of ready attachment to a wagon or other axle, and are adapted to be quickly and easily operated for the purpose described.

It is obvious that when desired the lubricant receptacles or reservoirs might be fixed on a support other than the axle without departing from the scope of my invention.

Having thus described myinvention, what I claim is- 1. In an axle-lubricator, the combination of an axle having suitable spindles, lubricant reservoirs or receptacles iixed at a suitable distance apart, conduits leading from said receptacles or reservoirs to the axle-spindles, followers arranged in the receptacles or reservoirs, and having stems provided with righthand threads and left-hand threads, respectively, and a turnbuckle interposed between the stems of the followers and having threaded apertures receivingthe same, substantially as specified.

2. In an aXle-lulnicator, the combination of an axle having spindles, lubricant reservoirs or receptacles fixed on the axle at a suitable distance apart, tubes leading' from the outer ends of the reservoirs to and through the axle-spindles t0 the surfaces thereof, folthreaded apertures receiving the same, sublowers arranged in the receptacles or reserstantially as specified.

voirs and havin stems extendin throu h the inner threads thereof, and prox ide d with I PERRY BARTLETT 5 right-hand threads and 1eft-hand threads, re- 1 Witnesses:

spectively, and a turnbuckle interposed be- FREDERIC E. ELMENDORF,

tween the stems of the followers and having W. F. MCCARTHY.
